DTC C2334 SAS neutral point not learned
 
 
cautionBefore replacing the ECU, ensure that the power supply circuit, the ground circuit and the communication circuit are normal.
 
 
OPERATION
The BSW-ECU (slave) communicates with the steering wheel sensor via the gateway-ECU, the BSW-ECU (master) and the CAN bus lines.
 
 
CHECK CONDITION
Electric motor switch is in the ON position.
 
 
DIAGNOSTIC FUNCTION AND TROUBLE JUDGMENT
When the BSW-ECU (slave) receives the signal, which indicates that the neutral position of the steering wheel sensor has not been learnt yet, the ECU will set DTC C2334.
 
 
TROUBLESHOOTING HINTS
  • Neutral position of steering wheel sensor not learned
  • Malfunction of the steering wheel sensor (incorporated in column switch assembly)
  • Malfunction of BSW-ECU (master/slave)
 
 
DIAGNOSIS
1. Using scan tool (M.U.T.-IIISE), read the BSW-ECU (master) DTC [Check if DTC C2334 is set in the BSW-ECU (master)].
2. Using scan tool (M.U.T.-IIISE), read the BSW-ECU (slave) DTC again.
3. Using scan tool (M.U.T.-IIISE), read the BSW-ECU (slave) DTC again.
